He did not keep on good terms with William the Conqueror, and in 1075, disregarding the King's prohibition, he married his sister Emma to Ralph Guader, Earl of Norfolk, at the famous bridal of Norwich.
Immediately afterwards, the two earls rebelled. Roger, who was to bring his force from the west to join forces with those of the Earl of Norfolk, was held in check at the River Severn by the Worcestershire fyrd, which the English Bishop Wulfstan, Walter de Lacy, and other Normans brought into the field against him.
On the collapse of his confederate's uprising, Roger was tried before the Great Council, deprived of his lands and earldom in 1075, and sentenced to perpetual imprisonment. He was released, with other political prisoners, at the death of William I in 1087.
Roger left two sons, Roger and Reginald. Both may have been born after his release in 1087.Roger received lands in the Savoy region and went on to head the House of Candia. He married one of the daughters of the Count of Geneva. He took the name Roger de Candie, leaving his descendants the castle of Candia and lands in northern Italy.
Reginald married Emmelind Ballon, the daughter of Hamelin de Balun of Abergavenny, and took her surname. He died before 1166, leaving his descendants the lordship of Much Marcle with its castle.
